DENDRO-SCOTT™ Ready-Made Tree Pit Liners are quick and easy to install and save time on jointing the membrane in situ.
They are 1m deep and can be folded to create sizes up to 1.9m in diameter. (See diagrams below).

If installed in a circular pit, the diameter measures 1.9m when fully extended, but the membrane can easily be folded, to create smaller sizes, as required.

If installed in a square pit, the membrane will measure 1.5m on each of the four sides. Naturally, it can be folder to create smaller sizes, or installed in a rectangular pit.
